QSC LS118: Powerful 18-inch subwoofer for impressive bass performance

The QSC LS118 sets new standards for subwoofer performance, offering powerful and impressive bass reproduction with a peak sound pressure level of 138 dB. Equipped with a specially developed 18-inch long excursion driver with direct dispersion, it delivers exceptional low frequencies for an intense listening experience.

Thanks to the energy-efficient Class D amplifier module with 4000 W peak power and integrated power factor correction, the LS118 is extremely energy-efficient without sacrificing performance. The innovative Acoustic Linear Phase (ALP) design, in combination with other QSC loudspeakers, ensures coherent and even sound reproduction throughout the venue.

Control and configuration is facilitated by the QSC SysNav (System Navigator) app, which allows users to design, monitor and customize individual subwoofers, entire arrays or groups. Integration into network systems is seamless thanks to digital audio-over-IP (Dante®), which enables compatibility with other devices and integration into the Q-SYS ecosystem.

For maximum flexibility, the LS118 offers two dispersion modes: omnidirectional or cardioid (at least two subwoofers are required for cardioid mode). The selectable DEEP mode provides an even deeper bass response, ideal for demanding audio applications.

The robust wooden housing with hard-wearing polyurea coating ensures durability even under intensive use. Transport and set-up are made easier by four low-noise, robust castors and M20 threaded sockets for speaker poles, array frames or ground stack adapters. The LS118 can be used both vertically and horizontally to meet the requirements of different setups.

The perfect complement to the LS118 are the LA108 and LA112 active line array speakers, which together offer an unrivaled sound experience. The QSC LS118 is the ideal choice for demanding audio professionals looking for maximum power and versatility in a subwoofer.
